From potential to kinetic and back again - with every swing.
The pendulum's potential energy is highest at the highest point of its swing and lowest at the lowest point. As the pendulum swings, potential energy is converted to kinetic energy and back again.
You can make a pendulum swing faster by increasing its initial height or by shortening the length of the pendulum. Both of these actions will result in a larger potential energy that will be converted into kinetic energy, causing the pendulum to swing faster.
The kinetic energy is greater at the bottom of the swing because the pendulum is moving fastest at that point. As the pendulum swings down, the potential energy is converted into kinetic energy, resulting in increased speed at the bottom.
In a pendulum, potential energy is converted to kinetic energy as the pendulum swings back and forth. When the pendulum reaches the highest point in its swing, it has maximum potential energy; as it moves downward, potential energy is converted to kinetic energy. At the lowest point, the pendulum has maximum kinetic energy. This energy conversion continues throughout the pendulum's motion.
The pendulum doesn't swing as high on the return swing because some of its potential energy is converted into kinetic energy during the forward swing. This kinetic energy is then converted back into potential energy as the pendulum swings back up. Some energy is also lost to air resistance and friction, resulting in less energy being available to lift the pendulum to its highest point.
At the start of a swing the pendulum has lots of potential energy but no kinetic energy. As it moves downwards the potential energy is converted into kinetic energy. In the upswing the kinetic energy is converted back into potential energy. Some of the energy is converted into heat by friction which is why the pendulum slows down.

In a swinging pendulum, energy is constantly being converted between potential energy (at the highest point of the swing) and kinetic energy (at the lowest point of the swing). The total energy remains constant, but it changes form as the pendulum moves back and forth.
A pendulum is fastest at the lowest point of its swing, where its kinetic energy is maximum. At this point, all the potential energy has been converted into kinetic energy, resulting in the highest speed of the pendulum.
A pendulum will lose energy in two ways: 1. by friction with the air, 2. by friction in its supporting bearing. Both these energy losses will produce heat.
This is a conservation of energy problem. When the pendulum starts out, it has gravitational potential energy; at the bottom of the swing, all of that has been converted to kinetic energy, and when it swings back up, back to gravitational potential energy (which is why speed is greatest at the bottom of the pendulum); in other words, there has to be the same amount of energy (PEgravitational = mass*gravity*height), where mass and gravity are constant.
As the pendulum stops swinging, its maximum kinetic energy (the initial energy at the beginning of the swing) decreases, and its potential energy increases. Once the pendulum stops, it will have zero kinetic energy and maximum potential energy.
In a pendulum clock, the potential energy stored in the raised weight or spring is converted into kinetic energy as the weight descends or spring unwinds. This kinetic energy is then transferred to the pendulum, causing it to swing back and forth. The energy is continuously converted between potential and kinetic as the pendulum oscillates, regulating the clock's movement.
